Application Bled December 16, i921. Seria-1 No. 522,848.

To all whom z't may concern.'

Be it known that'I, Ronn'r H. LINDSAY, citizen of the United States,residing at Houston, in the county of Harris and State Vof Texas, Vhaveinvented certain new and useful Improvements in a Still, of which the,following is a specification.

This invention relates to new, and useful limprovexnents in a still.

One object ofthewinvention is to'provide an apparatus of the characterdescribed whielrhas been speciallydesigned for the treatment of crudepetroleum, whereby the lighter elements may be readily separated fromthe heavier.

Another object of the invention is to provide an apparatus of thischaracter whereinv the residuum, remaining after the` separation ofthe-lighter elements therefrom, will also he rendered lighter' andeasier handled and ot' greater utility.

. W ith the ahove and other objects in view the invention has particularrelation torertain novel features ot construction, arrangement oi partsand use an example of which is given in this specitication andillustrated iu the accompanying drawings 4whereinz Figure l shows a sideelevation 'of the apparatns` showing the furnace walls in section, and,t

Figure 2 is an end view ot' the apparatus. Referring now more particulary to the drawings, the numeral l designates' an enclosing furnace, whosewall may be formed ot brick, concrete or other-suitable material. )Juivethis furnace there is located a tank 'l which contains the oil to hetreated. lieading t'roin the hottoni ot' this tank there is a down pipev3 which is controlled hy .the

gate alve l and whose lower end is connected into the T-section 5, .byine-ans ot which it is connected to the pipes (i. These latter arearranged in zigzag turns 2 iu vertical plane, within the t'urnac and atthe other end thereof they are connected into a tubular pipe -S throughwhich the residnuni is discharged.

VAbove the furnace there is arranged the outlet line 94 and thealternate coils are connected into this line through 'thev tubes 10.

'lhe oil to lie'treated circulates through the turns in the. directionindicated hy arrows iu Figure l` the lighter elements passq ing upthrough the tute lt) into the line l), and the residuuni passing oil'through the pipe S.

Underneath the turnsl are the pneumatic pressure lines ll. .ll` whichare connected to a suitahle pressure line 1:5. The pressure lines ll areprovided with the opstanding nozzles tti which are Iitted through thestull ing boxes ll otf :i'ltcin:ite .sections ot the turns T and ahovesaid nozzles these coil sections are restricted. as at l5.

The lui-nace is equipped with a suitable oil luu'ner lt which issupplied with fuel through'the line lT and which is connected to the airpressure line l2, through the tubular connection 1S. The lau-ner isarranged underneath the coils and heats them.

A\s the oil to he. treated circuit-ttes through the coils it is brokenup by the air jets from the. nozzles 13 and the lighter elements areseparated from the heavier and pass into vthe line. 9 whilethe residuuniis taken otf through tlie pipe'S above'stated.

\Vhat I' claimed is:v

A still including alfurnace, a tank above the furnace, a pipeleadingfrom the bottom ot' the tank, and t'orined into zig-zag turns l'viug ina vertical plane. within the Furnace and terminating in a dischargeoutlet,"an outlet lineA 4arranged ahove the furnace, a pneumaticpressure line beneath the turns of said pipe, opstanding nozzlesconnected into the pressure line, said nozzles extending into the lowerends of alternative turns o? said pipe, and` disposed to dischargepressure tluid into said turns with theeurrent of Huid llowingthroughsaid pipe, said turns beingy restricted above the respective nozzles,tubes connecting the turns, which said nozzles exii lter, into saidoutlet line.

In testimony whereof I have 'signed my naine.

ROBERT H. LINDSAY.
